Amanda Knox was seen riding her bicycle around Seattle Saturday before preparing her appeal against her murder conviction of British student Meredith Kercher. Knox, 26, cycled to the local Goodwill store in her hometown in Seattle, Wash., before preparing the appeal, The Daily Mail reports.

It has been a little over a month since she was sentenced to 28 years in prison for killing Kercher with her then-boyfriend, Raffaele Sollecito, who was also found guilty.

Kercher, 21, was found dead with her throat slit in the house she shared with Knox is Perugia, Italy on Nov. 2, 2007.

Knox and Sollecito were previously convicted of murdering Kercher in 2009, and were sentenced to 25 and 28 years, respectively. They were then acquitted and released in 2011 after the case was overturned in an appeals court. Knox returned home to Seattle, where she stayed when the case went to retrial last September. Then in late January, an Italian appeals court reconvicted Knox and Sollecito of slaying Kercher. Sollecito received a sentence of 25 years.

"I am frightened and saddened by this unjust verdict," Knox wrote after the ruling. "Having been found innocent before, I expected better from the Italian justice system."

The U.S. Supreme Court must now confirm Knox's guilty verdict before Italy can apply for her extradition back to Italy.

Last month, Knox claimed that Sollectio was trying to distance himself from her. She wrote on her blog: "Raffaele has plenty of reason for resentment, but not against me. The only reason he has been dragged into this is because he happens to be my alibi. He is collateral damage in the unreasonable, irresponsible and unrelenting scapegoating of the prosecution's grotesque caricature that is 'Foxy Knoxy'."

Rudy Guede, who Knox and Sollectio both pegged as Kercher's murderer, is serving a 16-year sentence for murdering and sexually assaulting Kercher.

During Guede's trial, he said he was at the murder scene, but that he was in the bathroom at the time of Kercher's attack. He said he saw "someone resembling Sollectio" fleeing the scene and "Knox outside the house" on the night of the murder. Guede's lawyer, Valter Biscotti, said Guede is now eligible for day release, and has been given permission to study history at an Italian university.
